The former Democratic congressional staffer who posted personal information about Republican senators online faces nearly 50 years in prison.

Jackson Cosko, a 27-year-old Washington, D.C., resident, was arrested Wednesday by U.S. Capitol Police when he was caught sneaking into the offices of Sen. Maggie Hassan, D-N.H., after 10 p.m. Tuesday and using an aide’s computer and log-in.

He was charged with five federal offenses: making public restricted personal information, making threats in interstate commerce, unauthorized access of a government computer, identity theft, and witness tampering.

The criminal complaint against him also charges him with second-degree burglary and unlawful entry, which are both criminal offenses in D.C.

[...]The maximum prison time total for the five federal offenses is 33 years, with the Washington offenses carrying a maximum of 15 years for second-degree burglary and another six months for unlawful entry.
